Transmission Cooler/Cooler lines

So the plate style as opposed to the tube/fin style, correct?
I haven’t bought one in over 30 years.
Any brand or size recommendations for in front of the radiator on a ‘72 Demon?

Look at Tru-Cool coolers. They're the same at the B&M plate coolers, but a lot less expensive. I run the M7B (8" x 11" x 1-1/2") in my 66 Dart.
